Abstract
A vertical axis wind turbine generator whose blade is allowed to stably operate according to a win force, with a simple structure. The generator is equipped with an arm whose proximal end is coupled to a rotating shaft and whose front edge is provided laterally to a rotating central axis line, and a blade mounted on the arm. A pair of divided blade plates is arranged in a V-shaped form. One sides of the blades are pivotally coupled together, while the opposite sides are provided in openable and closable manner. Coil springs are interposed between the blade plates and the arm. The blade plates are allowed to open or close according to wind directions and wind pressures, so that the rotation speed is regulated with a simple structure, enabling stable electric power generation.
